Hypericum plant named ‘Vericecla’

ABSTRACT

A new and distinct cultivar of  Hypericum  plant named ‘Vericecla’, characterized by its upright plant habit; durable dark green-colored leaves; freely flowering habit; large pale yellow-colored fruits; and good postproduction longevity.

Botanical designation: Hypericum androsaemum.

Cultivar denomination: ‘Vericelcla’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofHypericum, botanically known as Hypericum androsaemum and hereinafterreferred to by the name ‘Vericecla’.

The new Hypericum is a product of a planned breeding program conductedby the Inventor in Wieringerwerf, The Netherlands. The objective of thebreeding program is to create new cut flower Hypericum cultivars withnumerous attractive fruit coloration.

The new Hypericum originated from a cross-pollination made by theInventor in August, 2001 in Wieringerwerf, The Netherlands of aproprietary selection of Hypericum androsaemum identified as code number121 062, not patented, as the female, or seed parent with a proprietaryselection of Hypericum androsaemum identified as code number 222 258,not patented, as the male, or pollen, parent. The new Hypericum wasdiscovered and selected by the Inventor as a single flowering plantwithin the progeny of the stated cross-pollination in a controlledenvironment in Wieringerwerf, The Netherlands in July, 2003.

Asexual reproduction of the new cultivar by vegetative cuttings inWieringerwerf, The Netherlands, since August, 2003, has shown that theunique features of this new Hypericum are stable and reproduced true totype in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Vericecla have not been observed under allpossible environmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature and light intensitywithout, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Vericecla’. These characteristics incombination distinguish ‘Vericecla’ as a new and distinct cultivar ofHypericum:

-   -   1. Upright plant habit.    -   2. Durable dark green-colored leaves.    -   3. Freely flowering habit.    -   4. Large pale yellow-colored fruits.    -   5. Good postproduction longevity.

Plants of the new Hypericum differ from plants of the female parentselection in the following characteristics:

-   -   1. Plants of the new Hypericum have more compact and denser        inflorescences than plants of the female plant selection.    -   2. Plants of the new Hypericum have more rounded fruits than        plants of the female parent selection.

Plants of the new Hypericum differ from plants of the male parentselection in the following characteristics:

-   -   1. Plants of the new Hypericum have more upright flowering stems        than plants of the male parent selection.    -   2. Plants of the new Hypericum have stronger and darker        green-colored leaves than plants of the male parent selection.    -   3. Plants of the new Hypericum are more freely flowering than        plants of the male parent selection.    -   4. Plants of the new Hypericum and the male parent selection        differ in fruit coloration as plants of the male parent        selection have brown-colored fruits.

Plants of the new Hypericum can be compared to plants of the cultivarVerivocla, disclosed in U.S. Plant Pat. No. 16,326. In side-by-sidecomparisons conducted by the Inventor in Wieringerwerf, The Netherlands,plants of the new Hypericum differed from plants of the cultivarVerivocla in the following characteristics:

-   -   1. Plants of the new Hypericum were more upright than plants of        the cultivar Verivocla.    -   2. Plants of the new Hypericum had shorter flowering stems than        plants of the cultivar Verivocla.    -   3. Plants of the new Hypericum were more freely branching than        plants of the cultivar Verivocla.    -   4. Plants of the new Hypericum had longer flower pedicels than        plants of the cultivar Verivocla.    -   5. Plants of the new Hypericum had more rounded fruits than        plants of the cultivar Verivocla.
